Watching afr and checking plugs for damage and timing marks. E85 burns pretty clean. I was using track results but mostly just mph. The goal was to get the wot stutter eliminated.
Wot looked like .78ish, trying to watch oil pressure at the same time. From what I've read and been told .71-.75 is an e85 happy spot, but really whatever the engine is happy with.
I was driving it like I was leaving a stop light and Rolling into the throttle I was surprised it even had a 1.7 60ft. It felt so effortless. And with the 3.55 gears makes it pretty sweet. I bet 3.73 would be a nice happy gear.
